8 Claims.

This invention relates to improvements in vehicle wheel checking units and pertains particularly to an improved form of chock designed for use in securing motor vehicles againstmovement while being transported.

The primary object of the present invention is to provide an improved chock block which is lighter than the forms at Apresent in use and, therefore, cheaper to construct and because of its peculiar construction is less likely to split when in use than are the present type of blocks.

Another object of the invention is to provide an improved chock block which is so designed that it may be constructed of scrap pieces of wood which would otherwise be thrown away.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not coniined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the .invention as expressed in the appended claims.

In the drawing:-

Figure 1 is a view in side elevation of the chock block embodying the present invention;

Figure 2 is a view in top plan of the same;

Figure 3 is a view in rear elevation of the block.

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, it will be seen that the present improved chock block comprises two side members, each of which is indicated by the numeral I, and an intermediate member which is indicated by the numeral 2. These side members I comprise portions of planks or boards, such, for example, as those referred to as 2 X 6s or 2 x 8s, which are out in the form of a trapezium whereby they each have the parallel side edges 3 and 4, a right angular transverse end edge 5, and an oblique end edge 6. The oblique edge 6 of each of the side members constitutes the base or foot therefor, while the edge 5 constitutes the top of the member.

'Ihese members I, when in use, are arranged in spaced parallel relation and their opposing faces are recessed or cut out from the top edges 5 downwardly, thus forming the vertical recess walls 'I which parallel the outer side faces of the members and the transverse shoulder walls 8 3 and 4.

Disposed between vthe members I and resting in I the recesses in their inner faces, upon the shoulders 8 and abutting the vertical walls 1, is the intermediate spacer member 2. This member 2 isof a length vequal to the width of the members I and is secured between and to the same by nails or other suitable securing elements 9 which are driven transversely through the side members I and into rthe member 2.

The top edge surface of each member I is cut down along the inner corner and transversely curved as indicated at Ill and the top surface of the intermediate member 2-is also cut away to form the slightly depressed transverse curved surface I I'. These surfaces I0 and II are joined so as to form a complete or unbroken depressed curvature in the top of the chock block in which the tire of a motor vehicle wheel may rest.

When the chock block unit is set up it rests solely upon the base or bottom edges 6 of the members I.V Thus the curved top surface'thereof, which is made up of the surfaces I0 and Il, will be oblique to the'floor surface upon which the unit is placed. In addition to the surfaces I0 and I I being transverselycurved they are slightly longitudinally curved as indicated at I2 so that both the transverse and circumferential curvatures of the tire will be accommodated.

In order to facilitate securing the members to la supporting surface, the members are provided with bores I3 and I4 through which the securing nails or screws may be extended. As shown, the bores I3 are formed through the toe of each member I from the top edge I downwardly to pass through the bottom edge 6 adjacent the longitudinal center thereof and the passages I4 are formed in the members I from the outer sides thereof to extend obliquely downwardly and open through the bottom edges 6 thereof, also substantially upon the longitudinal center of these edges.

From the` foregoing it will be readily apparent that the block embodying the present invention may be easily and economically constructed and due to its construction it will be strong but light in weight sothat it will not add materially to the weight to which the carrier is subjected.

Having thus described the invention, what is claimed is:-

l., A chock, comprising a pair of members disposed in spaced relation and each having an oblique supporting end edge, and an intermediate member between and secured to the pair oi?l members and supported solely thereby, the opposite end edges of the pair of members and the intermediate member each being presented for contact by a body and coacting for the support of the same.

2. A chock, comprising a pair of elongated relatively fiat members each having an end edge oblique to its side edges, said members being supported in spaced relation upon their oblique edges, and a member interposed between and connecting said first members adjacent the ends of the same remote from the oblique edges, said rst members having the said remote ends formed to coact with said interposed member to support a vehicle wheel.

3. A chock, comprising a pair of elongated relatively flat members each having an end edge oblique to its side edges, said members being supported in spaced relation upon their oblique edges, and a member interposed between and connecting said first members, said interposed member being supported solely by the pair of members and in spaced relation to the surface upon which the pair of members rest and further having its top surface fiush with the surfaces of the adjacent top edges of the pair' of -members whereby the said top edges and the interposed member will be engaged by and coact to support a. vehicle wheel. i

4. A chock, comprising av pair of elongated flat members of trapezoidal contour, each" of said members having one end edge at right angles to the side edges and resting upon the opposite end edge as a base, said members being in spaced relation, shoulder means extending transversely of the opposed faces of the members, and a body interposed between the members and resting upon said shoulders and secured to the members, said body extending transversely of the members and coacting with' the top edges of the members to support a vehicle wheel. Y

5. A chock, comprising a pair of bodies of trapezoidal contour having a parallel side edge and an end edge disposedobliquely thereto, said end edges of the bodies constituting supporting basesv therefor, said bodies being disposed in spaced side by side relation, means yforming shoulders transversely of the opposed faces of the bodies, a body interposed between said first bodies and resting upon said shoulders, and means securing the interposed body to the rst bodies.

6. A chock, comprising a pair of bodies of trapezoidal contour having a parallel side edge and an end edge disposed obliquely thereto, said end edges of the bodies constituting supporting bases therefor, said bodies being disposed in spaced side by side relation, means forming shoulders transversely of the opposed faces of .the bodies, a body interposed between said rst bodies and resting ugpon said shoulders, and means securing the interposed body to the first bodies, said iirst bodies being cut downwardly lfrom the outer corners of those end edges opposite the oblique edges, to the inner corners and said interposed body having its top surface transversely curved and coacting with the cut down surfaces of the rst bodies to form a transversely curved depression against which a vehicle wheel may rest.

7. A chock, comprising a pair of bodies of substantially trapezoidal contour in which one edge extends oblique to two parallel side edges to form a a supporting base, said bodies being disposed in spaced side by side relation, a recess formed in the side face of each body opposing the other body to form transverse shoulders, a connecting body supported upon said shoulders in said reu cesses and secured to the first bodies, and said rst bodies at the edges opposite the base edge and said connecting body being transversely curved to form a vehicle tire receiving depression. 8. A chock, comprising two members disposed in side by side relation and each having an end cut obliquely to form a supporting base, and a body disposed between the members and extending across the ends of the same remote from the oblique bases and supported solely by the two members, the said other ends and the interposed body being formed to provide an arcuate surface against which the tread of a vehicle tire may abut.
